Centimeter (abbreviation: cm): is a unit of length in the SI metric system, equal to one hundredth of a metre, centi being the prefix for a factor of 1/100. The centimetre was the base unit of length in the now deprecated centimetre–gram–second (CGS) system of units.
Kilometer (abbreviation: km): is a unit of length in the SI metric system, equal to one thousand metres (kilo- being the prefix for 1000). It is now the measurement unit used officially for expressing distances between geographical places on land in most of the world countries.
How to Convert Centimeters to Kilometers
Example: How many kilometers are equivalent to 72.09 centimeters?
As;
1 centimeters = 1.0E-5 kilometers
72.09 centimeters = Y kilometers
Assuming Y is the answer, and by criss-cross principle;
Y equals 72.09 times 1.0E-5 over 1
(i.e.) Y = 72.09 * 1.0E-5 / 1 = 0.0007209 kilometers
Answer is: 0.0007209 kilometers are equivalent to 72.09 centimeters.
